VDS_E_ISCSI_LOGOUT_FAILED
LogoutFromTarget operates on the target ID and performs a manual logout from all iSCSI sessions to that target. This status is the direct failure result for that operation. It is broader than losing one TCP connection, because an iSCSI target can have session state that the initiator service must tear down and VDS exposes logout as an asynchronous operation.
Why this state matters
Do not confuse the code with VDS_E_ISCSI_LOGOUT_INCOMPLETE. The incomplete status explicitly means at least one session failed while others may have logged out. This code reports the logout operation as failed; the caller should still enumerate actual remaining sessions before deciding whether anything changed.
Diagnostic focus
- Record the target VDS object ID and wait for the asynchronous logout result to finish before checking state.
- Enumerate remaining sessions after the failure; do not assume the pre-call session set is unchanged.
- Check whether storage is still mounted or in active use by applications before repeatedly forcing session teardown.
- Inspect initiator-service diagnostics and target logs for logout/connection recovery events from the same time window.
